jhendersonHDF 90429f5e7d Implement support for complex number datatypes (#4630)
* Implement support for complex number datatypes

Adds the new datatype class H5T_COMPLEX

Adds the new API function H5Tcomplex_create which creates a complex
number datatype from an ID of a base floating-point datatype

Adds the new feature check macros H5_HAVE_COMPLEX_NUMBERS and
H5_HAVE_C99_COMPLEX_NUMBERS

Adds the new datatype size macros H5_SIZEOF_FLOAT_COMPLEX,
H5_SIZEOF_DOUBLE_COMPLEX and H5_SIZEOF_LONG_DOUBLE_COMPLEX

Adds the new datatype ID macros H5T_NATIVE_FLOAT_COMPLEX,
H5T_NATIVE_DOUBLE_COMPLEX, H5T_NATIVE_LDOUBLE_COMPLEX,
H5T_CPLX_IEEE_F16LE, H5T_CPLX_IEEE_F16BE,
H5T_CPLX_IEEE_F32LE, H5T_CPLX_IEEE_F32BE,
H5T_CPLX_IEEE_F64LE and H5T_CPLX_IEEE_F64BE

Adds hard and soft datatype conversion paths between complex number
datatypes and all the integer and floating-point datatypes, as well as
between other complex number datatypes

Adds a special conversion path between complex number datatypes and
array or compound datatypes where the in-memory layout of data is the
same between the datatypes and data can be converted directly

Adds support for complex number datatypes to the h5dump, h5ls and
h5diff/ph5diff tools. Allows h5dump '-m' option to change floating-point
printing format for float complex and double complex datatypes, as well
as long double complex if it has the same size as double complex

Adds minimal support to the h5watch and h5import tools

Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the Java wrappers. Also adds initial,
untested support to the JNI for future use with HDFView

Adds support for just the H5T_COMPLEX datatype class to the Fortran
wrappers

Adds support for the predefined complex number datatypes and
H5Tcomplex_create function to the high level library H5LT interface
for use with the H5LTtext_to_dtype and H5LTdtype_to_text functions

Changes some usages of "complex" in the library since it conflicts with
the "complex" keyword from the complex.h header. Also changes various
usages of the word "complex" throughout the library to distinguish
compound datatypes from complex datatypes.

Dana Robinson 786b03317a Fix remaining calloc param reversals (#5018)
gcc 14 identifies likely places where the sizeof() call is used
for the first parameter to calloc(). This PR fixes the remaining
places in the library where this occurs and reworks a few other
allocations to be more uniform.
2024-10-28 06:58:28 -07:00
Quincey Koziol 97e1ed4fc8 Refactor allocation of API context (#4942)
Since each API context is local to a thread, use the stack to
store the context instead of allocating & releasing it each time.
This improves performance (slightly), reduces alloc/free calls,
and eliminates the H5FL package from the push & pop operations,
which helps simplify threadsafe operation.

One effect of this change is that the H5VLstart_lib_state /
H5VLfinish_lib_state API routines for pass through connector
authors now require a parameter that can be used to store
the library's context. It was probably a mistake to assume
that these two routines would not do this previously, so this
is essentially a bug fix for them.

Some other minor things:

 * Added API context push+pop operations to cache tests
  (I'm not actually certain why this was working before) and
  a few other places
* Cleaned up a bunch of warnings in test code (calloc args, mainly)
* Made header file inclusions more standard in some source files

Dana Robinson a99d620172 Clean up random number generator code (#4338)
* Clean up random number generator code

Depending on the platform, we use a mix of random, rand, and rand_r
to generate pseudo-random numbers, along with a messy set of ifdefs
in H5private.h. We are not a cryptographic library, only use random
numbers in our test code, and have no need for anything more than the
C standard's (s)rand(). There's no point dithering about using rand()
vs random() when we're also doing bad things like using mod to
restrict the range, which introduces bias.

Also removes CMake/configure checks for rand_r and random

* Remove random/rand_r checks from build system

* Fix missed HDrandom after GitHub merge

jhendersonHDF 330b80a266 Add support for _Float16 16-bit floating point type (#4065)
Fixed some conversion issues with Clang due to problematic undefined
behavior when casting a negative floating-point value to an integer

Fixed a bug in the library's software integer to floating-point
conversion function where a user's conversion exception function
returning H5T_CONV_UNHANDLED in the case of overflows would result in
incorrect data after conversion

Added configure checks for functions and macros related to _Float16
usage since some compilers expose the datatype but not the functions or
macros

Fixed a dt_arith test failure when H5_WANT_DCONV_EXCEPTION isn't defined

Fixed a few warnings from not explicitly casting some _Float16 variables
upwards

2022-07-26 14:45:46 -07:00
27bb358f7a Subfiling VFD (#1883)
* Added support for vector I/O calls to the VFD layer, and
associated test code.  Note that this includes the optimization
to allow shortened sizes and types arrays to allow more space
efficient representations of vectors in which all entries are
of the same size and/or type.  See the Selection I/o RFC for
further details.

Tested serial and parallel, debug and production on Charis.
       serial and parallel debug only on Jelly.

* ran code formatter

quick serial build and test on jelly

* Add H5FD_read_selection() and H5FD_write_selection().  Currently only
translate to scalar calls.  Fix const buf in H5FD_write_vector().

* Format source

* Fix comments

* Add selection I/O to chunk code, used when: not using chunk cache, no
datatype conversion, no I/O filters, no page buffer, not using collective
I/O.  Requires global variable H5_use_selection_io_g be set to TRUE.
Implemented selection to vector I/O transaltion at the file driver
layer.

* Fix formatting unrelated to previous change to stop github from
complaining.

* Add full API support for selection I/O.  Add tests for this.

* Implement selection I/O for contiguous datasets.  Fix bug in selection
I/O translation.  Add const qualifiers to some internal selection I/O
routines to maintain const-correctness while avoiding memcpys.

* Added vector read / write support to the MPIO VFD, with associated
test code (see testpar/t_vfd.c).

Note that this implementation does NOT support vector entries of
size greater than 2 GB.  This must be repaired before release,
but it should be good enough for correctness testing.

As MPIO requires vector I/O requests to be sorted in increasing
address order, also added a vector sort utility in H5FDint.c  This
function is tested in passing by the MPIO vector I/O extension.

In passing, repaired a bug in size / type vector extension management
in H5FD_read/write_vector()

Tested parallel debug and production on charis and Jelly.

* Ran source code formatter

* Add support for independent parallel I/O with selection I/O.  Add
HDF5_USE_SELECTION_IO env var to control selection I/O (default off).

* Implement parallel collective support for selection I/O.

* Fix comments and run formatter.

* Update selection IO branch with develop (#1215)

Merged branch 'develop' into selection_io

* Sync with develop (#1262)

Updated the branch with develop changes.

* Implement big I/O support for vector I/O requests in the MPIO file
driver.

* Free arrays in H5FD__mpio_read/write_vector() as soon as they're not
needed, to cut down on memory usage during I/O.

* Address comments from code review.  Fix const warnings with
H5S_SEL_ITER_INIT().

* Committing clang-format changes

* Feature/subfiling (#1464)

* Initial checkin of merged sub-filing VFD.

Passes regression tests (debug/shared/paralle) on Jelly.
However, bugs and many compiler warnings remain -- not suitable
for merge to develop.

* Minor mods to src/H5FDsubfile_mpi.c to address errors reported by autogen.sh

* Code formatting run -- no test

* Merged my subfiling code fixes into the new selection_io_branch

* Forgot to add the FindMERCURY.cmake file. This will probably disappear soon

* attempting to make a more reliable subfile file open which doesn't return errors. For some unknown reason, the regular posix open will occasionally fail to create a subfile.  Some better error handling for file close has been added.

* added NULL option for H5FD_subfiling_config_t in H5Pset_fapl_subfiling (#1034)

* NULL option automatically stacks IOC VFD for subfiling and returns a valid fapl.
* added doxygen subfiling APIs

* Various fixes which allow the IOR benchmark to run correctly

* Lots of updates including the packaging up of the mercury_util source files to enable easier builds for our Benchmarking

* Interim checkin of selection_io_with_subfiling_vfd branch

    Moddified testpar/t_vfd.c to test the subfiling vfd with default configuration.
    Must update this code to run with a variety of configurations -- most particularly
    multiple IO concentrators, and stripe depth small enough to test the other IO
    concentrators.

    testpar/t_vfd.c exposed a large number of race condidtions -- symtoms included:

      1) Crashes (usually seg faults)

      2) Heap corruption

      3) Stack corruption

      4) Double frees of heap space

      5) Hangs

      6) Out of order execution of I/O requests / violations of POSIX semantics

      7) Swapped write requests

        Items 1 - 4 turned out to be primarily caused by file close issues --
    specifically, the main I/O concentrator thread and its pool of worker threads
    were not being shut down properly on file close.  Addressing this issue in
    combination with some other minor fixes seems to have addressed these issues.

        Items 5 & 6 appear to have been caused by issue of I/O requests to the
    thread pool in an order that did not maintain POSIX semantics.  A rewrite of
    the I/O request dispatch code appears to have solved these issues.

        Item 7 seems to have been caused by multiple write requests from a given
    rank being read by the wrong worker thread.  Code to issue "unique" tags for
    each write request via the ACK message appears to have cleaned this up.

        Note that the code is still in poor condtition.  A partial list of known
    defects includes:

     a) Race condiditon on file close that allows superblock writes to arrive
        at the I/O concentrator after it has been shutdown.  This defect is
        most evident when testpar/t_subfiling_vfd is run with 8 ranks.

     b) No error reporting from I/O concentrators -- must design and implement
        this.  For now, mostly just asserts, which suggests that it should be
        run in debug mode.

     c) Much commented out and/or un-used code.

     d) Code orgnaization

     e) Build system with bits of Mercury is awkward -- think of shifting
        to pthreads with our own thread pool code.

     f) Need to add native support for vector and selection I/O to the subfiling
        VFD.

     g) Need to review, and posibly rework configuration code.

     h) Need to store subfile configuration data in a superblock extension message,
        and add code to use this data on file open.

     i) Test code is inadequate -- expect more issues as it is extended.

        In particular, there is no unit test code for the I/O request dispatch code.
        While I think it is correct at present, we need test code to verify this.

        Similarly, we need to test with multiple I/O concentrators and much smaller
        stripe depth.

    My actual code changes were limited to:

          src/H5FDioc.c
          src/H5FDioc_threads.c
          src/H5FDsubfile_int.c
          src/H5FDsubfile_mpi.c
          src/H5FDsubfiling.c
          src/H5FDsubfiling.h
          src/H5FDsubfiling_priv.h
          testpar/t_subfiling_vfd.c
          testpar/t_vfd.c

    I'm not sure what is going on with the deletions in src/mercury/src/util.

* Merge branch 'selection_io' into selection_io_with_subfiling_vfd (#1265)

* Added script to join subfiles into a single HDF5 file (#1350)

* Modified  H5FD__subfiling_query() to report that the sub-filing VFD supports MPI
This exposed issues with truncate and get EOF in the sub-filing VFD.
I believe I have addressed these issues (get EOF not as fully tested as it should be), howeer,
it exposed race conditions resulting in hangs.  As of this writing, I have not been able
to chase these down.

Note that the tests that expose these race conditions are in testpar/t_subfiling_vfd.c, and
are currently skipped.  Unskip these tests to reproduce the race conditions.

tested (to the extent possible) debug/parallel on charis and jelly.

Quincey Koziol 33ea1ada24 [svn-r25496] Description:
Merge 64-bit ID changes from branch to trunk.  (Plus a few minor cleanups
that aren't on the branch)

Tested on:
    Mac OSX/64 10.9.4 (amazon) w/C++ & FORTRAN
    (h5committested on branch already for a week)
2014-07-30 15:55:14 -05:00
Dana Robinson e6cace9ee4 [svn-r24376] Updated all code to use HDmalloc, HDcalloc, and HDfree.
Prep work for adding a memory free function, part of HDFFV-8551.

Tested on:
    32-bit LE linux (jam) 
        * with C++, Fortran
        * with thread safety on

    These are minor changes (almost entirely renaming foo functions
    to HDfoo) that don't change functionality.  This should not
    require a full commit test.

Quincey Koziol 88a94bbe7f [svn-r22646] Description:
Changes resulting from Klocwork static analysis tool, from Mark Miller
@ LLNL (miller86@llnl.gov).

Tested on:
    Mac OS X/64 10.7.4 (amazon) w/debug, C++ & FORTRAN, using gcc 4.7.x
    (too minor to require h5committest)
2012-08-08 18:01:20 -05:00
Raymond Lu a5522454a5 [svn-r21258] Issue 7674 - clang compiler reported an error with line 334:
temp_point->l = (unsigned long long)((i * 100 + j * 1000) * n);
The value can overflow the signed int before being converted to unsigned long long.  So I changed it to 
   temp_point->l = (unsigned long long)((i * 40 + j * 400) * n);
to keep it under the maximal value.

Tested on jam.  Simple change.

Quincey Koziol a777619a6b [svn-r21121] Description:
Switch from H5P_DATASET_ACCESS_DEFAULT to H5P_DEFAULT for calls to
H5Rdereference2().

Tested on:
    Mac OS X/32 10.6.8 (amazon) w/debug
    (too minor to require h5committest)
2011-07-18 18:12:28 -05:00
Raymond Lu 304f19d730 [svn-r21117] Issue 2763 - I added a new parameter of object access property list to the function H5Rdereference. It's called H5Rdereference2 now. H5Rdereference function has been deprecated to H5Rdereference1. I also added some test cases in trefer.c.
Tested on jam, heiwa, and koala.
